To all whom, it may concern:

' Be it known that I, CHARLES'F. 'l.- KAN- DELER, a citizen of the United States, resid, ing at Chicago, in thecounty of Cook and State of Illinois, have invented a new and useful Improvement in Fireproof Floor Construction, of which the following is a specifi- 'cationl e My invention relates-to an improved construction of tiered floors, such as are provided in auditoriums, particularly those (including the galleries) of theaters; and my object is to render such floors of light, but strong and durable, structure and thoroughly ,i'reproof. 'Referring to the accompanying drawings, Figure 1 is a broken sectionalview, the sec- `tion being taken lengthwise `of theiloor-` beams, showing Amy improved construction as used in the main or gallery door of a theater; yFig. 2, abroken section taken at the line 2 on Fig. 1 and viewed in the direction of the arrrow, and Fig. 3 a broken-section taken at the line 3 on Fig, 1 and viewed in the direction of the arrow.

A denotes one of the oor-beams (Lbeams being the preferred form used,) which are provided at suitable invervals in d esired number, and placed in proper relative position tol incline downward toward the front of the au-V ditorium. At suitable intervals upon each beam A are fastened in upright position the posts B, (shown in their preferred form of angle-irons,)bolted or riveted through one side r"to a Side of the beam to present the other side r Iiatwise to the front. Each postB has fastened to its front side fr two angle-brackets` q and ql', the position of the former beingadjacent to the upper edge of the inclined beam A, and that of the latter .being at the upper end of the post, and their relative positions being such (the posts B should all be of vequal or substantially equal len gth) that thebracket q on one post -will be on the same horizontal plane with the bracket q immediately behind it. The forwardly-proj ectin g portions of each row of brackets q afford seats to which are fastened, as by means of bolts, the angle-irons p in a manner to present their sides r2 forward in vertical position, and the forward projecting portionsof each row of brackets q afford seats to which are fastened, as by means of bolts,'the angle-irons p in a manner to presenti no. 581,636.

of angle-irons 1J p' thus afford bearings forthe floor Cof each tier C, which floor is composed of a base o, formed preferably of corrugatedsheet metal and a iilliug -n thereon of concrete or analogous material, which should' extend flush with the upper edges of the sides fr? r3 of the opposing anglelironsp and p', and whereby the sides r2 of the former ador-d a binding for protection, along the Aforward edges of the tier, to the concrete.` At the `back of each tier C is extended, across the posts B and between the base` of the horizontal side 4of each bracket q' to the floorC, expanded metal or'wire-clotli backing m, upon which a coveringm,of concrete or analogous material, is applied, preferably of a thickness tocause it to extend iiush with the. forward edges of the horizontal portions ofthe brackets q.

What I claim as new, and desire to secure. e

by Letters Patent, isy V '1. In a fireproof tiered-floor construction, the combination of the inclined floor-beams having posts fastened to them at intervals,said posts carrying'upper and lower seats connect- 'ing the posts crossw'ise ofthe beams, fireproof floors on said seats and freproof backs extending between the tiers, substantiallyas described.- e

2. In a iireproof tiered-floor construction, the combination of the inclined floor-beams havingposts fastened to them at intervals, angle-irons p connecting the posts at their upper ends crosswise of thebeams, angle-irons p' similarly connecting saidposts below their upperl ends, iireproof floors on said angleirons and tireproof beams between the tiers,

substantially as described.

3. In aiireproof floor construction, the combination of the inclined door-'beams having posts fastened to them at intervals, brackets fastened to each post, to extend forward thereon, one near the floor-beams and one near the upper end of the post, flreproof floors supported in tiers on said brackets, and flrel proof backs extending between the tiers, substantially as described.

4. In a iireproof tiered-floorconstruction,

the combination of the inclined floor-beams having postsfastened to them at intervals, brackets q and q fastened to each post, to extend forward thereon, `respectively near the 6.
